I'm in 100% agreement with @lewm. There is something else that I hear from sliver wire that has not yet been mentioned here and that is leanness. To my ear silver wire has a lot less meat on the bone, meaning lean sounding. One person that I know is willing to accept that leanness to get the big increase in detail he is getting with an Audioquest Angel interconnect on his turntable.
Copper vs. Silver tonearm wire
The subject of tonearm wire was touched on in a related thread on tonearms. Long standing friend rauliruegas strongly advocates silver. I tried it and switched back to copper. I need to re-wire my HW-40 and because my hands are getting shakey with age, must now delegate the task so I want to get it right. VPI told me today that their upscale wire, Nordost, used to be silver, but they switched back to copper because too many people found the silver to be too bright. That was exactly what my impression was when I last tried silver. Thoughts?
